The slope is 3
1.) distribute the 3 to both the X and 17 so that your equation looks like this: y-5= 3X-51
2.) add 5 to both sides and you will end up with the equation: y=3X-46
3.) since this is in slope intercept form now (y=mx+b), we can conclude that m(or the slope)= 3
> this is the sign for the larger absolute value
Answer:
-1266
Step-by-step explanation:


Answer:

Step-by-step explanation:
We are given the following in the question:
Sample size, n = 67
Variance = 3.85
We have to find 80% confidence interval for the population variance of the weights.
Degree of freedom = 67 - 1 = 66
Level of significance = 0.2
Chi square critical value for lower tail =

Chi square critical value for upper tail =

80% confidence interval:

Putting values, we get,

Thus, (3.13,4.91) is the required 80% confidence interval for the population variance of the weights.
30*4 = 120 (120 oranges=total oranges needed)
120/20=6
Scott need 6 boxes of oranges
